Librescu was among the thirty-three people killed in the Virginia Tech massacre on April 16, 2007. He was killed during a class in the Norris Hall Engineering Building. He was 76 years old.[6] Librescu held the door of his classroom shut while the gunman Cho Seung-hui was attempting to enter it. He was shot through the door but was able to prevent the gunman from entering the classroom until his students had escaped through the windows[7][8]. A number of Librescu’s students have called him a hero because of his actions, with one student, Asael Arad, saying that all the professor’s students “lived because of him.”[9]
In all tragedies come our heros.
